ISL8105AIRZ

DC DC Switching Controllers Overview

The ISL8105AIRZ is a synchronous buck switching controller manufactured by Renesas Electronics Corporation. It operates with a fixed switching frequency of 600 kHz and supports an input voltage range of 6.5 V to 14.4 V. The device provides a single adjustable output ranging from 600 mV to 12 V, capable of driving loads up to 25 A. It features a maximum duty cycle of 100% and includes current limit and enable control characteristics. The component is housed in a 10-DFN (3x3) package with an exposed pad and functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'AIRZ' against official Renesas documentation to confirm the exact pinout and thermal pad configuration. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check for recent Product Change Notifications regarding manufacturing site or material updates. Ensure design compatibility with the 10-DFN footprint and exposed pad soldering process.

DC DC Switching Controllers Selection Notes

Select this component when a compact synchronous buck solution is required for inputs between 6.5 V and 14.4 V. The 600 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 25 A output capability meets the load requirements and that the SOIC/DFN thermal performance is adequate for the application environment.
